Product Description

The hydraulic pump assembly of GVO brand for the main pump of the SK135SR-8 SK140-8 SH130-5 SH120A5 excavator is compatible with the SK135SR-8 SK140-8 SH130-5 SH120A5  model hydraulic pump components. It features high-quality performance.

The products are directly supplied from the manufacturer without any middlemen adding extra prices. The cost performance is far superior to similar products. There is an ample stock of goods in stock, and once you place an order, the order will be quickly processed and dispatched. There is no need for long waiting periods.

The entire machine undergoes strict pressure testing upon leaving the factory, ensuring stable quality. At the same time, we provide comprehensive after-sales warranty, and the technical team will follow up throughout the process. Maintenance inquiries can be responded to at any time.

Product Descriptio

This main hydraulic pump for SK135SR-8 and SK140-8 excavators is the core assembly of the entire machine's hydraulic power system. It adopts a dual-variable piston pump integrated structure design, integrating an electromagnetic proportional regulator. The oil port layout, mounting flange, and transmission shaft specifications are fully in line with the original vehicle components. It can directly replace the faulty old pump without the need to modify the pipelines, brackets, and electronic control circuits. It is a core supporting component for equipment major repairs, second-hand machine refurbishment, and hydraulic system fault repair.

The pump body main body is made by casting high-strength ductile iron as a whole, with excellent anti-shock, anti-vibration, and anti-deformation performance. Under continuous vibration and high-pressure impact conditions at the construction site, the shell is less likely to develop cracks and deformations. The internal cylinder, piston, flow distributor, and swing components, as the core friction pairs, are made of high-hardness wear-resistant alloy materials. They undergo precise grinding and multi-layer heat treatment hardening processes to significantly enhance the wear resistance and anti-scratch ability of the components, effectively resisting wear caused by hydraulic oil impurities, and reducing the leakage problem inside the pump. The entire sealing system uses high-pressure-resistant and aging-resistant fluorine rubber seals, which can adapt to the alternating high and low temperatures and continuous high-pressure impact in harsh working environments. It still maintains reliable sealing effect under long-term operation, avoiding oil leakage, oil seepage, and preventing pressure attenuation and abnormal increase in fuel consumption caused by hydraulic leakage. Each hydraulic pump will undergo a complete set of performance tests on a professional hydraulic testing bench before leaving the factory. It will be sequentially tested for no-load, full-load pressure, flow output characteristics, sensitivity of the electromagnetic regulator response, and internal leakage indicators. Only when all parameters meet the standards can it be stored and shipped. This strictly controls product quality and avoids quality risks such as unstable pressure and regulator failure.
